lrepresents the casing which may be of suitable form.

o provide governing parts for the mechanism, which may embrace a reservoir 2, one wall of which is formed by a partition 3, the reservoir being arranged to receive a suitable fluid, shown at, in which a screw "0, shown as a conveyer-screw, is arrangedto same, the extent, of movement thereof being controlled by the speed of said discharge. \Ve have shown this end-member as comprising an inverted cup having an end 21 against which the discharge takes place."

The wall of the cup is received about the tube and is preferably guided in its axial movement by guide-ribs 22 on the tube.

23 is a )ositioning arm actuated by the QIlCllilClllbEEl', preferably through the medium of an arm 2st pivoted on a rod 25 in the casing, the arm 2-t being shown as a bellcrank arm, one of the branches of which is provided with a fork 27, the tines of which have articulation with pins 28 on the hub of the end-member, this end-member having axial movement on the shaft 6. The other branch of the arm 24 is provided with a segment-gear 30 which meshes with a segment-gear 31 on anarm'32 rigid with the arm 23, the arms 23, 32, being pivoted about a rod 33 inthe casing, the parts being retracted by a spring 84:.

36 is a slide which'is positioned by the arm 23, with which it has connection as by means of a pin 37 on the arm bein received between lugs 38 on the slide, these lugs forming a slot in which said pin is received, the pin and slot having connection through 'an opening 89 in the partition 3. The slide is positioned between rollers 41 for afford-.

ing case of movement of the slide, the position of the slide determining the moment of actuation of the initiating mechanism of" our improved device, which in the form shown, also embraces pins and slots hereinafter described. A

For operating the actuated parts hereinafter describedwe provide friction-wheels 51, 52, secured to a shaft 53 journaled in bearings 54 of rocker-arms'55 pivoted on a shaft 56 in bearings 57 of the casing. The friction-wheels 51, 52, are preferably continuously rotated during operation of the device, for'which purpose the shaft 53 has a gear 58 thereon and is meshed by a gear 59 on a shaft 60 journaled in bearings 61 in the casing. The shaft '60 is arranged to be ro tated in suitable manner, preferably by the controlled device, as by the rear axle 9 of the automobile which is propelled, and the speed of. which is arranged to be regulated by our improved device, which connection may be effected in suitable manner, as

-manner hereinafter stated.

noeaaea through a flexible connection 62 which may be driven by the driven axle through bevel-' gears 68, 10.

71, 71 71, 71, are a series of sets of cams, the cams of each set rotating together. The cam-sets 71 and 71 are loosely journaled about a rod secured in the casing and are held in endwise relation by sleeves 69 and 69 and the cam-sets 71 and 71 are loosely journaled about a rod 68 secured in the casing and are held in endwise relation by sleeves 69 and 69. Each of these sets comprises the following parts desig nated by the numerals applied thereto with the exponents a, b, c, d, corresponding to the set of cams to which the said exponents respectively belong, namely: Each set of cams comprises'an intermittently rotatable friction-Wheel 72 provided with a clearance recess 7 3, a locating recess 74 being provided in a hub 75 from which a pin 76' projects, there being further a cam 77, and a cam 78, the latter being shown as an cccentricallyplaced roller on a pin 79 on the hub. The friction-wheel 72, cams 77, 78, and,the pins and locating recesses,,are located in different planes extending transverse to the rotary axis of the cam-set. The clearance recesses 73 "73, and 73 73, are normally positioned opposite the respective friction wheels 51, 52, the latter being urged toward the former by springs 66 between the casing and the rocker-arms 55. Limiting rods 67 are threaded into the rocker-arms and passed through holes 81 in the casing, the outer ends of the limiting rods being threaded for receiving nuts 82 which adjustably limit the inward movement of said arms and distance the continuously-rotating friction-wheels from the Walls'of the clearance recesses in the intermittently rotating friction-wheels.- The cam-sets are normally soweighted that the pins thereon will nor.

mally drop. The cams 77, and 77 are atthe pin sides of the cam-sets 71, 71, while the cam-sets 7 7 77 are at substantially the opposite sides of said cam-sets, these latter cams however being counter-weighted by the counterweight lugs 83 and'83 The pins 76, 7 6", 76, 6, respectively coact with slots 85*, 85, 85, 85, respectively .in flanges 86, 87 of the slide 36, the pins being adapted to selectively drop through said slots by gravity when the several pins and slots register with each other for the purpose and in The conveyor-screw and its attendant parts act as a governing mechanism, the connection of which with the slide and the driven element control the direction of movement and the position of the slide, this position being dependent on the speed of the driven element, and the direction of movement of the slide being dependent on whether the driven element is operating at an increasing or a decreasing speed. The direction of movement ofthe sllde during an lncreaslng speed is indicated by the arrow ,9 and its direction of movement during de-- creasing speed is indicated by the arrow h. It will be assumed that the controlled element is a speed-changing mechanism similar Y to that shown in either of our aforesaid applications, Serial Nos. 635,127 and 654,869,

in which three speeds are provided for, namely, low speed, an intermediate speed and a high speed, the steps of increasing speed being from low to intermediate and from intermediatefto high, and the steps of decreasing speed being from high to intermediate and from intermediate to low. When the slide moves for changes of speed by steps from low to high, the slide moves in the direction of the arrow 9, and .when.

changes of. speedare effected by steps from 5 high to low, the. said slide moves in'the direction of the arrow h.

The cam-sets? 1 and 71", arranged end to end, and. the slots 85 and 85 in the slide, are instrumental in eifectingfinitiation of increasing speed relation in the controlled device; and thecam-sets 71 and 71 also arranged end to end, and the slots 85 and 85 in said slide, areinstrumental in efiecting initiation of decreasing speedrelation, the cam-sets'il and 7l ,-and thecam-sets "(1 and- 71, being placed opposite each other, whereby compact arrangement of parts is obtained. The cam-sets 71 and 71 rotate intermittently in the direction of the arrow i.

and the cam-sets 71 and 71 rotate intermittently in the direction of the arrow is. The cam-set 71- is instrumental in efiecting change from low to intermediate speed, and the mechanism is shown in relation for effecting such a step as the first step in the operation of the device, the elements being' shown in low speed'relation, being their nor mal relation or positions of rest. In effect- 1ng such change from low to lntermedlate speed, the pin 76 drops .through the slot 85 the walls of which are shown slanting in the direction of the arrow 9 and approaching each others transverse planes for permitting the pin 76 -to pass through said "slot only when the said slide moves In the direction of the arrow g. The cam 71 is efieotive in initiating a change-in speed from 'in- "termediate to high, for effecting which the pin 76 drops through the slot" 85. In returning from high to low speeds by steps as aforesaid, the cam-set 71 is effective for a speed change from high to intermediate, to accomplish which the pin 7 6 'is' arranged to drop through the recess 85, the walls of which latter slant in the direction of the I arrow .h, and project toward each others cross-sectional planes, for permitting the pin 76 to pass through said slot only when the slide moves in the direction of the arrow h.

The cam-set 71 is effective-for changing from intermediate to low speed, in which case the pin 76 drops through the slot 85. The pins and slots are so arranged that only a pin in the next inhreasing or decreasing step of speed may drop through a slot. Thus when the operation of the device is begun, the pin 76* will be resting on the-flange 86' and the speed increasing, caused for instance .by the opening of the throttle of the engine,

the slide will be moved in the direction of the arrow 9 by' the governing mechanism,

and when the slot 85 reaches the pin the pin will drop through the slot, thereby permitting a partial rotation of the cam-set 71 and moving the clearance recess 73* of the friction-wheel 72 with relation to the friction-wheel 51 and permitting engagement between the frictional periphery of the friction-wheel 72 with the frictional periphery of the friction-wheel 51-, for im- I partinga rotation to the cam-set 71*, the pin tained, or the pin 76 may pass through the slot 85 if a decrease of speed from intermediate to low is obtained, dependent on resistance to propulsion of the operated de-.'

vice, or supply of motive power through the usual throttle of the explosive engine.

By means of our improveddevice change in speed relation in the speed changing mechanism may be controlled by the usual .throttle of the explosive motor, for if the supply offuel is reduced, a decrease in speed relation will follow, or if the supply of fuel is increased, an-increase'in speed relation, within the capacity of the motive power with relation to resistance en countered,- will follow. If a high speed has been obtained, and a decrease from high to intermediate is efiected, the slide, which has in the meantime moved throughout its range in the direction of the arrow 9, returns 1n the direction of the arrow, h, and the pin 76 drops through the slot 85 Any pin which has last dropped through a slot is arrested in elevated position with relation to its. flange, and the pin upon the opposite cam-set is released, which, with the form of the slots mentioned, secures sequential operation of parts and prevents interference of operation by' one of thelparts with the other. For positioning the pins and permitting operation of the cam-sets, We provide parts which coact with the locating recesses 74:, 7 1", 74$, 74:, shown in the form of rollers 91, 91", 91, 91 These" rollers are arranged to be received in the locatingrecesses of those cam-sets the pins of which are momentarily to be held in raised positions, while the rollers for those cam-sets, the pins of which are arranged to be dropped intooperative relation, are momentarily held in disengaged relations, permitting that oneof the latter pins which registers with a slot in the slide, which will permit it, to drop through. For accomplishing this We provide an oscillating framework 92 comprising side frames 93, 9&, rigidly secured frame .is preferably accomplished by spring together by tie-bolts 95, 96, the tie-bolt 95 being surrounded by a sleeve 97 against the ends of which the hubs 98, 99, of the sideframes are clamped. The sleeve'97 has rock ing fitin a bearing 100 011 a bracket 101 secured to the casing. The framework or oscillating frame also has contact-faces 105?, 105", 1051, 105 thereon, respectively arranged .to be engaged by the eccentric cams 78 78, 78, 789 The oscillating frame is rocked by the said eccentric cams contacting the said contact-faces respectively, for moving the respective positioning rollers out of selective positioning recesses; and intoother selective positioning recesses. The latter part of the rocking movements of the pressure means. For this purpose one of the side-frames is provided with a lug 107 upon which a pin 108 is located, the pin The arm v112 is received through a swivelpiece 116 on the arm 110, a spring 117 being interposed. between said swivel-piece and the hearing'of arm 112, thespring urging the arm 112 to either, side of a right line between the axes of the arms 110 and 112 at which said swivel-piece may be placed. When therefore, the rocker-arm has been shifted suificiently for shifting said swivelpiece to either side of said right line, 'the movement of the rocker-arm is continued by the action of the spring, so that theiposi tioning rollers may yieldingly contact the peripheral faces of their respective canrsets and ride thereon until the positioning reces'ses on said cam-setsfcome opposite the rollers, whereupon the rollers will snap into the recesses for positioning said respective cam-sets.

It will be noted thatthe' positioning rollers 91 and 91, on the ,side-frame.93,have the cam-sets upon which they operate 10- catedvbetween them, while the contact-faces.

105, 105, on said side-frame, acted .on by the said cam-sets, are located between said cam-sets, whereby the cant-set which acts upon one of said contact-faces shifts the positioning roller therefor into engagement with said cam-set, releases the opposite positioning roller on said side-frame from the opposite cam-set, and places the opposite contact-face into position for contact by the eccentric roller on said opposite cam-set. On the other hand the positioning rollers on the side-frame 94 are located between the ram-sets upon which they operate and the contact-faces on said, side'frame have said cam-sets located between them. By these arrangements opposite cam-sets are alternately acted on. The respective cam-sets also have the actuating came 77 77 7 7, 77 thereon, which act on the actuated mechanism or controlling element or elements, shown as a pairof levers 122, 123, which may have suitable connection with an operated device, heretofore mentioned, as through flexible connections 124, 125, which may connect with said operated'device and correspond to the flexible connections illustrated in our. aforesaid applications, Serial Nos. 635,127 and 654,869.

The "lever 122 has a bearing 128 about a stud 129 threaded into a pedestal 130 in the casing. Theflever is shown as a bell-crank lever with one of the arms of which the flexible connection 124 connects, its other. arm supportin a roller 131 to be contacted by either cam 2 7 or 77. A spring 132 re-- tracts the lever, which also has a lug 133 thereon arranged to contact a lug 134 on the casing,. acting as a retracting stop for the lever. The lever 123 has a bearing 135 journaled about the shaft 60. The flexible connection 125 connects with one of its arms and its other arm has thereon a roller 136 arranged to be contacted by either cam 7 7 or 77".

137 is a spring for retracting the lever 123. For limitin the retraction a suitable stop is provided, 5 own as a lug 138 on the lever and a lug 139 011 the. casing.

One of the levers is actuated when the slide 36 move's in one direction and the other lever is actuated when said slide moves in the opposite direction. Thus when the slide moves in the direction ofthe arrow g,- the cam-sets 71 and 71", which are laterally arranged with relation to each other and control a speed change in increasin ratio from low to intermediate and interme iate to high speed, are operated, in turn actuating the lever 123, and when said slide moves in the opposite direction for decreasing speeds as from high to intermediate and from intermediate to low, the cam-sets 71 and 71,

which are laterally arranged with relation to eachother, actuate the lever 122. The levers in turn eifect corresponding operations in the controlled device, respectively causing changes in speed respectivelyin increasing and decreasing rat-1o,

the speed limit of the device being propelled I or driven, and we have exemplified these means as consisting of the following instrumentalities, namely: 141 is a primary slide and142 is a secondary slide, theprimary slide sliding on the secondary slidejin a slideway 143, and held thereto by' screws 144 threaded into the secondary slide androceived through slots 145 in the.- primary slide. A lug 146 extends from the primary slide through a slot 147 in the secondary 5 slide and has 'a contact-piece 148 shown adj ustable thereon as by a clamp-screw 149 received througha slot 150 in the contact-piece and .threaded into the lug 146, the contactpiece being provided with a contact-lip 151; 20155 is a striker-part arranged to engage-the contact-pieceand is shown as a pin actuated by the arm 23, arrangement being made so that the speed-limit device may be rendered inactive, as by moving the pin out of range of the contact-lip, which in the present exemplificationis accomplished by mounting the pin on an arm 156 pivoted-to. an-eritension 157 of the arm 23 at 158. The arm 156 may be swung into forward position with 1'6, =lation to the slide 36, as shown in fulllines in Fig. 8 or it maybe swung in rearward position, as shown indotted lines in said figure,

whereby, with the adjustment of the contactpiece148, a wide range of speed limit may be obtained for our improved device, and

the limit set within-an placing the arm 156 .invertical position, as

'shownin dotted lines in said figure. The

. The friction-wheel 165 is mounted on a stud 171 secured to a lever-172 pivoted on a pin 173 in a bearing 174 on e casing. The friction-wheel 165 is heldtoward the friction-wheel 164'by a spring 175 and isjheld out of contact with said-friction-wheel by a 6i) limitingrod176-secured to said 'lever and received through a bearing 177 on the casing, the .same being adjustable by a nut 178. The spring surrounds the rod and is located between said bearing and lever." -When the 8.111123131110 766. 'outof lts normal or restang.

The friction-wheel with the raised friction surfaces continuously rotating will thereuponmake engagement with the tongue by one ofits raised friction surfaces, for

pinching the tongue between that raised friction surface and the friction surface of the-friction-wheel 164, whereby the primary slide is drawn lengthwise between the frioso tionrwheels. The lug 146 will meanwhile have moved in its slot for contacting the end. wall of said slot, whereby the secondary slide is drawn with the primary'slide by the action of saidfriction-wheels. As soon how- 35 ever,'as one of the interruptions 166 reaches a posit-ion opposite the tongue-extensiom'the latter will be released, and both said slides retracted. spring 182 between said secondary slide and the casing retracts both.9o said slides, and a light spring 183 between the primary slide and the secondary slide retracts the primary slide to an extezitpermitted by the position of the pin 155 with relation to the contact-lip 151 or to the full extent permitted by the slot 147. If the position of the pin 155 does not permit retract-ionf of theprimaryv slide to an extent tobring its tongue-extension out of range of the raised friction surfaces, repeated actuations of theslides will take place, .until the device operated by said slides has effected a retardation of speed within the speed limit for which the device has been set. If our improved device is applied. to an automo- 5 bile, for instance the speed of travel of the same may be limited to a given number of miles per hour. The device operated byjsaid slides may be any suitable mechanism, and

may be for instance a spark-interrupter of 1 0 an explosive engine or a throttle control for the same. We have illustrated the same as 'a throttle control, whereby. the supply of.

fuel to theflengine is controlled and decreased or cut off by theactuatio'n of the 5 slides, depending on the extent of movement of the throttle. Thus 186'is a lever pivoted 'at-187" to the casing. It has an end 188,.re-
